Abstract

The operation of air coolers of railway air conditioning (AC) systems is characterized by considerable variations in current heat loads according to actual climatic conditions on the route lines. This causes increased changes of refrigerant flows. Over filling the air cooler coils by liquid refrigerant recirculation enables excluding a decrease in heat flux within variations in current heat loads and provides increasing the heat efficiency of air coolers compared with conventional air coolers with complete refrigerant evaporation and superheated vapor at the exit. Thus a larger deviation of current heat load on railway route lines are permited without falling air cooler heat efficiency. The method to determine the rational design heat load on air coolers of railway AC systems, providing closed to maximum refrigeration output generation over considered time period, was developed.
